It seems to run fine. It's odd. If I turn the power up at all on the Edge is very obvious under load. It'll buck and smoke a ton. With the Edge off, it runs normal as long as i'm not getting on it. I can definitly tell it's missing some but it doesn't sound like it's going to explode like it does with the Edge on.
